Java '；A4J'；是未定义的

我对ie7上的ajax4jsf库有问题，它会给我错误“A4J未定义”，但这个错误不会出现在firefox和chrome上

我使用的图书馆 myfaces1.1.5和ajax4jsf1.1

这是我的

XYZ未定义

这是一个典型的Javascript错误。由于它在真正的WebBrowser中运行良好，所以服务器端的一切都非常好

我唯一想到的是使用/生成的javascript库中存在冲突。我建议升级到可用的最新版本，并将其全部对齐

我们有一个集群环境，IHS将流量定向到两个节点。部署未与一个节点正确同步，导致a4J未定义错误间歇性出现。重新启动节点和服务器，应用程序开始正常工作
